quarkus CDI：拦截器没有绑定

Question

我严格按照这里的教程(https://quarkus.io/guides/cdi#interceptors), and write a simple interceptor based on this mini example (https://github.com/quarkusio/quarkus-quickstarts/tree/main/getting-started)

我的拦截器：

package org.acme.getting.started;

import javax.annotation.Priority;
import javax.interceptor.AroundInvoke;
import javax.interceptor.Interceptor;
import javax.interceptor.InvocationContext;

@Logged
@Priority(2020)
@Interceptor
public class InvocationLogger {

    @AroundInvoke
    Object logInvocation(InvocationContext context) {
        System.out.println("Entering method:" + context.getMethod().getName());

        try {
            Object ret = context.proceed();
            return ret;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }

    }

}

绑定注解：

package org.acme.getting.started;

import java.lang.annotation.Target;
import java.lang.annotation.Retention;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import static java.lang.annotation.ElementType.METHOD;
import static java.lang.annotation.ElementType.TYPE;;

@Retention(value = RUNTIME)
@Target(value = { METHOD, TYPE })
public @interface Logged {

}

我尝试绑定的服务：

package org.acme.getting.started;

import javax.enterprise.context.ApplicationScoped;

@ApplicationScoped
public class GreetingService {

    @Logged
    public String greeting(String name) {
        return "hello " + name;
    }

}

但是我得到 Interceptor has no bindings 错误：

        at java.base/java.lang.Thread.run(Thread.java:829)
        at org.jboss.threads.JBossThread.run(JBossThread.java:501)

我做错了什么吗？

缺少的部分是将 @InterceptorBinding 注释添加到 public @interface Logged 注释。
